Steve Coogan and Carol Vorderman have publicly lent their support to the Liberal Democrats as the party conference kicks off with a call for electoral reform and tactical voting.

Statistics from the party said the Conservatives now have 56% of seats in the Commons, despite only receiving 44% of total vote share at the last election.

Lib Dem parliamentary representation in the Commons amounts to a mere 1.6%, even though they secured 11.6% of the vote.

The party has long called for the current “first past the post” system to be scrapped and be replaced with “proportional representation” – where the percentage of the votes a party gets across the country determines the number of MPs they send to parliament.

And now they have celebrity backing, with actor and comedian Mr Coogan using a video message played at a conference rally in Bournemouth to say the current electoral process “robs millions of people of their vote” and “millions of people’s voices go unheard”.

Ms Vorderman – best known for her time on Countdown – agreed with the need for change in her own video message to the gathering, saying: “We desperately need to end a system where only marginal seats matter, end a system which delivers parliaments that fail to accurately reflect votes cast and end a system where only the winner’s votes count.

“It doesn’t deliver parliaments that properly reflect the will of the nation.”

But to be able to make that change, both stars called for the public to be tactical in how they used their votes when the next national ballot comes.

Ms Vorderman said it was “absolutely vital that we come together to defeat the Tories”, adding tactical voting on a seat by seat basis was “the first step” towards change.

And while admitting he normally votes Labour and was not a member of the Lib Dems “despite the beard and the fleece”, Mr Coogan added: “Where I live in Lewes, the candidate best placed to kick the Tories out is the Lib Dem candidate, so I’ll vote for them.”

Speaking to Sky News in the run up to conference, Lib Dem MP Labour Moran said proportional representation would be “on the agenda” as the party “hasn’t lost its roots”.

But critics of the system say it could allow more fringe parties with extreme views to get seats in the Commons.

At the rally, Lib Dem leader Sir Ed Davey – who will appear on Sky News’ Sunday Morning with Trevor Phillips today – closed proceedings with the party’s giant clock, which it used to hammer home its message that “time’s up” Tories after its successful local election results in May.

He told the gathered MPs, councillors and activists: “While the Conservatives have counted the last four years in fines for partying during COVID, in scandal upon scandal, in the prime ministers that have left in disgrace and the lettuces that outlast them, we actually have something to be proud of.

“We can count our four years with by-election victory after by-election victory, with making history with the size of the majorities we’ve overturned and with our stunning local election success. “

He added: “This government is living on borrowed time. We know it. They know it. And when they finally decide to call time on so many years of shambles and sleaze, the Liberal Democrats will be ready.”
